The Hidden Cost of the Cloud: Data Centers, AI, and Mexico’s Water Crisis

The Guardian reports here on fears that the rapid expansion of data centers in Mexico - whilst contributing to their economic growth and creating new jobs - might have severe environmental consequences.

In the quiet industrial parks of Querétaro, Mexico, a technological revolution is underway. Towering stacks of servers whirr inside massive, temperature-controlled rooms, forming the beating heart of our digital lives. These are data centers, the "lungs" of our connected world, as Amet Novillo, Managing Director of Equinix Mexico, aptly describes them. With tech giants like Amazon, Google, and Microsoft pouring billions into building such facilities, Querétaro is quickly becoming a tech hub. But behind the glowing blue lights of progress lurk environmental challenges that could turn this digital boom into a crisis for the region.

The Power-Hungry World of Data Centers

Data centers, at their core, are warehouses packed with computers that work 24/7 to process everything from your latest Google search to video calls. The demand for electricity is massive, and keeping the servers cool requires even more energy and, in many cases, vast amounts of water. These high-tech facilities aren't just expensive to build—they're costly to maintain in terms of natural resources.

Tech companies like Amazon, Microsoft, and Google are pledging green initiatives, with promises of 100% renewable energy and water-positive operations by 2030. For example, Amazon claims its new air-cooled data centers in Querétaro won't drain the region's already scarce water supply. However, critics argue that the region's fragile infrastructure may not be able to handle the demands of these massive server farms.

A Double-Edged Sword for Querétaro

On the surface, the economic benefits of data centers seem clear. In Querétaro alone, the new wave of investments is expected to contribute billions to the Mexican economy, create jobs, and turn the state into a high-tech powerhouse. Yet, this comes with a steep environmental cost.

The region’s water supply is already stretched thin, with local aquifers overexploited for years. Aqueduct II, built in 2011 to transport water from rural areas to Querétaro city, was intended to alleviate some of these pressures. But with industrial expansion and climate change causing more frequent droughts, even this solution has fallen short. In Maconí, a small town along Aqueduct II, community leader Alejandro Ortiz has seen firsthand the toll this has taken on local residents. Springs once relied upon for water have dried up, and the government has yet to fully deliver on promises of a steady water supply.

In the face of such tensions, tech companies are presenting their projects as part of the solution. Google, for instance, points to machine learning tools that optimize energy use at its data centers, while OpenAI’s CEO, Sam Altman, has gone so far as to suggest that AI may one day help develop breakthrough energy sources like nuclear fusion. However, these promises are a long way off from solving the immediate challenges facing Querétaro’s environment.

A Global Problem with Local Impact

Querétaro’s dilemma is not unique. Across Latin America and the world, data centers are springing up to support the ever-growing demands of our digital age, raising concerns about sustainability. The International Energy Agency reports that data centers, cryptocurrencies, and AI technologies consumed nearly 2% of global electricity in 2022, with projections that this could double by 2026.

For regions like Querétaro, which rely heavily on fossil fuels for power generation, the environmental impact is undeniable. Every server rack not only uses water but also contributes to carbon emissions, as the majority of Mexico’s electricity comes from thermal power stations.

While governments and tech companies explore solutions—such as investments in solar and wind energy—the pressure is mounting. Without a transparent accounting of the real costs in terms of water and electricity, critics argue that the social and environmental toll may outweigh the economic benefits.

A Path Forward?

The debate about data centers in Querétaro highlights the complexities of balancing economic growth with sustainability. On one hand, the arrival of big tech could transform the region into a global player in the digital economy. On the other, the strain on local resources—particularly water—poses a serious threat to the well-being of its citizens.

For students studying economics, Querétaro offers a compelling case study of the possible trade-offs between economic development and environmental preservation. As the world becomes more reliant on digital infrastructure, the question remains: how can we build a tech-driven future without draining the planet’s most precious resources?
